ABSTRACT:
Fluent material such as mixed concrete to be molded into blocks is contained with a supply hopper for discharge of a predetermined quantity of such material to a mold. The hopper has a discharge opening at one side thereof, rather than at its bottom, so that material discharged from the hopper exits along a substantially horizontal path for reception in a mold supported adjacent the discharge opening. A partition is movable through material in the hopper to divide the contents thereof into upper and lower portions, the upper portion of which is supported on the partition and the lower portion of which is pushed through the hopper's discharge opening by a pusher blade carried by the partition. The leading end portion of the partition moves beyond the hopper's discharge opening and supports a quantity of the fluent material so that, upon return movement of the partition, the material on the lip is pushed off the latter adjacent the discharge opening in readiness to be discharged to the mold upon the next discharge movement of the pusher. The movable parts of the apparatus are housed within a sound absorbing enclosure having an opening through which molded blocks may pass, such opening being opened and closed in timed relation to the molding and discharge of such block.
